My main informant on the goings-on in Amersham said that the guy who runs La Roche Gym is the son of the owner of that parade of shops and the redevelopment has been on the cards for a while. Apparently that is why a few shops (Complete Bedrooms, Holland and Barratt) have relocated. Apparently HSBC are planning to move into one of the vacant units on the other side of the high street (Starbucks perhaps).
